MATLAB: Plotting doubt: making a curve with points

Question

Hi all, I have the following code:

figure
COPlin=Y./Yg;
plot(AATnew,COPlin)
axis([-10 80 0 1])

I want to make a curve, but Matlab is doing lot of lines between the points. What I want to obtain is a unique curve that put together all the points.

I would be glad if you could help me:)

Answer 1

I am not exactly certain what the problem is, but if my guess is correct, the sort function may be the solution:

AATnew = randi(90,20,1)-10;         % ‘AATnew’ is a (20x1) array
COPlin = rand(20,1);                % ‘COPlin’ is a (20x1) array
[Ms,Mi] = sort(AATnew);             % Sort ‘AATnew’, keeping indices
figure(1)
plot(AATnew,COPlin,'-*')            % Plot Original UNSORTED data
grid
figure(2)
plot(AATnew(Mi),COPlin(Mi),'-*')    % Plot SORTED data
grid
